Bozeman Science: Thermodynamics and P v Diagrams
In this video Paul Andersen explains how the First Law of Thermodynamics applies to an ideal gas in a piston. A pressure-volume graph can be used to determine the type of thermodynamic process. Included is a discussion of and P-V diagram...

Bozeman Science: Entropy
Entropy is simply the dispersion of matter or energy. Paul Andersen begins with a series of video that show the natural direction of processes. According to the second law of thermodynamics the entropy may never decrease in a closed...

Bozeman Science: Spontaneous Processes
In this video, Paul Andersen discriminates between spontaneous (or thermodynamically favored) processes and those that are not spontaneous. A spontaneous process requires no external energy source. If the enthalpy change in a reaction is...

Crash Course Chemistry #13: Ideal Gas Problems
Find put how the ideal gas "law" often becomes little more than the ideal gas estimate when it comes to what gases do naturally. But it's a close enough estimate in enough situations that it's very valuable to know. In this episode, Hank...

Crash Course Chemistry #12: The Ideal Gas Law
Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally and mathematically. The bad news is...
Crash Course
Crash Course Chemistry #14: Real Gases
Hank bursts our ideal gas law bubble, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected for volume because...
Crash Course
Crash Course Physics #23: Thermodynamics
Have you ever heard of a Perpetual Motion Machine? More to the point, have you ever heard of why Perpetual Motion Machines are impossible? One of the reasons is because of the first law of thermodynamics! In this video [10:04] episode of...
